mabl-mcp-server: Instructions file for Gemini CLI

GEMINI.md

mabl-mcp-server GEMINI.md is an instructions file for Gemini CLI from mablhq/mabl-mcp-server. It costs 413 tokens per session, scanned A, original, MIT.

Instructions for using the mabl MCP server from Gemini CLI. mabl is a hosted service for browser testing, and MCP is a way for an AI tool to call an external service.

In plain words
What is it for?
Finding mabl workspaces, working with tests and plans, analysing failed runs, and using mabl's AI test tools when the workspace allows them.
Why use it?
It explains how to sign in, select a workspace, interpret mabl IDs, and investigate failures correctly.

Instructions file for Gemini CLI

Written for Gemini CLI: the file is GEMINI.md.

This is mablhq/mabl-mcp-server's own configuration. It tells Gemini CLI how to work on mabl-mcp-server itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything mabl-mcp-server configures →

Reuse

Borrowing it

Nothing to install: this file belongs to mablhq/mabl-mcp-server. Take a copy, put it at the same path in your own repository, and replace the rules that are about this project with yours.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

mabl-mcp-server GEMINI.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

mabl

This extension connects to the hosted mabl MCP server (https://mcp.mabl.com/mcp), giving you access to the mabl tests, plans, and results for the workspaces your mabl account can reach. The first connection opens a browser to sign in with your mabl identity; after that the token is cached.

Working with mabl tools

  • Most tools need a workspace. Call list_mabl_workspaces first and reuse the ID, unless the user names a workspace explicitly.
  • mabl IDs carry a type suffix, and tools expect the right one: -j test, -jr test run, -p plan, -pr plan run, -f flow, -a application, -v deployment event. When a user pastes an ID, read the suffix before choosing a tool — a test ID will not work where a run ID is required.
  • Start from a failure, not a list. For "why did this fail", go to the AI failure analysis for the specific failed run rather than paging through runs.
  • Some tools are AI-powered (failure analysis, results analysis, cloud test generation) and require the corresponding mabl AI entitlements on the workspace. They can take 10-30s, and a permission error usually means the entitlement is missing rather than the call being wrong.

Reference

Calling tools/list shows exactly what the server exposes for your account, which is authoritative over any list written down here.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
